Exercise 6 Page 61

Let's calculate the perimeter and area separately.

Perimeter

In general, the perimeter of a figure is the sum of its side lengths. In this case, we have a square. A square has $4$ equal sides, so we can find its perimeter using the following formula. In this formula, $a$ is the length of each side. From the diagram, we know that $a$ is equal to $11\text{ft}.$ Substituting this value into the formula, we can calculate $P.$ The square's perimeter is $44$ ft.

Area

To find the area of the square, we will use the formula for calculating the area of a square. We have been given that the side length $s$ is equal to $11\text{ft}.$ To find the area of the square, we will substitute this value into the formula to calculate $A.$ The area of the square is $121{\text{ft}}^2.$
